Fig. 2 a plan in partial horizontal section Fig. 3 an end elevation;

' Fi 4 a fragmentary vertical section show- .ing t e automatic drain pan tilting mechanism, and

F i 5 a fragmentary end elevation showing t across-head in a partially withdrawn position.

The base member is conveniently formed from sheet metal and comprises a medial trough portion 10, end standards 11, 11,

laterally extending aprons 12, 12 between the and standards, and side guards 13, 13 at each end of each apron. The end standards are formed in a common and wellrknown manner to serve as supports for the bearing vblocks 1 5, 15 of the lower roller 16 and as, guides for the bearing blocks 17, 17 of the upper roller 18.

ach end standard comprises an end plate 11' 'segmentally notched at its upper end as indicated at- 11". Each end standard also comprises a vertical plate 20, parallel with plate 11' and inwardly" spaced therefrom, said plate forming part of the guiding and positioin means for the bearing blocks.

This p ate 20 is provided medially with a'vertical slot 21 open at its upper end, the width of said slot being such as to receive 0 and guide a boss 22 of the-carrier 23 for the upper bearing block 17. Carrier 23 is vertically movable within a cross-head 35 which brid es between the end standards, downwar movement of said carrier being limited by inturned lips 36 carried by the cross-head.

"membe v w A number of different forms of pivotal 55 which is circular for the major portion urged upon roller 16 with It will be readily understood that the boss 22 may be omitted, in which case slot 21 will be narrowed .to the diameter of the shaft of i the upper roller.

Each end wall 35 of cross-head' 5 is y;

rounded, as indicated at 35", to fit into notch 11'. Pivoted at 40 to each end wall 35' of cross-head 35 is the upper end of a link 41,

the lower end of which is pivoted to the base connection between links 41 and the base may, of course, be adopted, without depart from the spirit of my invention.

in the present drawing I show-a pivotal so connection which serves effectively to yieldingly retain the upper roller in active rela-- tionship with the lower roller.

Secured to each end wall 11, conveniently by spot-welding during process of assembly, as

is a plate provided at its outer end with an ou'twardlydisplaced portion" 51v and an inwardly directedtongue 52 which, in elevation, is an arcuate annulus, as indicated at 52', having a medial flattened outer face 52". 70

The angular extent of portion 52 is slightly less than180 degrees. Each link 41, near its lower end is provided with a perforation of its extent and of a diameter suchthatthe annular finger 52',may be projected thereinto. This perforation 55, at its lowermost portion, is rovided with a fiat seat 55' upon which the attened portion 52" may rest.

Arranged within cross-head 35 is a leaf a0 spring the ends of which formyielding abutments for bearing blocks '17.

The lengths of links 41 are such that, when the parts are in the positions shown in Fig. 3, spring 60 will be stressed and roller 18 a desired degree of initial pressure.

Upon the insertion of material between the two rollers 16 and 18, roller .18 will yield ppwardly against the action of spring 60.

By exerting a comparatively slight force laterally upon cross-head said cross-head will pivot upon the lower ends of links 41 and, as soon as the pivotal connections are carried to one side of the medial plane of the structure, the spring 60 will serve to further displace the upper ends of links 41 from vertical position, thereby freeing roller 18 from roller 16. Thereupon, the operator, by lifting the lower end of the cross-head may withdraw said lower end, and the upper roller, upwardly.

The trough portion 10 of the base is medially perforated at 71 and below this perforation is pivoted, at 72, a tilting drain pan 73 which may be tilted to either side of a medial position so as to direct water laterally beneath one or the other of the aprons 12.

In order that the tilting of the drain pan 73 may be automatic I secure to said drain pan at its middle an upwardly extending flexible wiper 75, which may be conveniently of soft rubber, and this wiper has a'vertical 5 extent sufficient to bring its upper end lightly ;into engagement with the periphery of the lower roller 16. Wiper 75, in its medial position, is in the medial vertical plane of the lower roller 16 so that rotation of roller 16 in either direction will automatically force ;the wiper, in the direction of rotation, to

one side or the other of said medial plane and thereby automatically tilt the drain pan so that the flow of water thereover will be in a direction opposite to the direction of imovement of the rollers at the crotch be tween them. 4 a

I claim as my invention;

1. A wringer comprising a base having end standards, supports for a lower roller and vertical guides for an upper roller, a crosshead bridging between the end standards, two links each pivoted at its upper end to the cross-head and at its lower end to thebase, the pivotal connections of said links being so arranged as to lie substantially in the vertical axial plane of the rollers when the parts are in active position, and spring means carried by the cross-head and forming yielding abutrnents for the upper roller.

2.A wringer of the character specified in claim 1 wherein the pivotal connection between each link and the base comprises an arcuate finger, and an arcuate perforation receiving said finger.

3. A wringer of the character specified in claim 1 wherein the pivotal connection between the lower end of each link and the base comprises an arcuate finger having an intermediate flattened portion, and an arcuate perforation having a flattened portion upon which the flattened portion of the finger may seat when the link is in medial vertical position.
